The low-level RF (LLRF) system at the European XFEL, DESY, is of major importance for high-performant and reliable operation. Faults here can jeopardize the overall operation. Therefore, the trip event logger is currently developed, - a fault diagnosis tool to detect errors online, inform the operators and trigger automatic supervisory actions. Further goals are to provide information for a fault tree and event tree analysis as well as a database of labeled faultydata sets for offline analysis. The tool is based on the C++ framework ChimeraTK Application Core. With this close interconnection to the control system it is possible not only to monitor but also to intervene as it is of great importance for supervisory tasks. The core of the tool consists of fault analysis modules ranging from simple ones (e.g., limit checking) to advanced ones (model-based, machine learning, etc.). Within this poster the architecture and the implementation of the trip event logger are presented.
